Those violations at Mavrik Aire include falsifying a medical clearance application after a DUI conviction and falsely representing an airplane's maximum allowed takeoff weight in a maintenance record, according to the Federal Aviation Administration.

FAA agents served Craig Schweitzer with two revocation letters this week, agency spokesman Allen Kenitzer said. The agency concludes in the documents that it had to move fast on the revocation because "an emergency exists related to safety in air commerce."

Two Alaska state troopers and a trooper trainee accompanied two FAA agents to Schweitzer's home Tuesday night to serve the revocation letters, trooper spokeswoman Megan Peters said. The FAA had asked for state support, she said.

The letters give Schweitzer notice of the revocation of his pilot's license, his airplane mechanic's license and his operations certificate for Mavrik Aire.

The move blocks Schweitzer from flying and Mavrik from operating its standard charter services.

Mavrik Aire issued a written statement on Wednesday asserting that guided hunting, fishing and viewing trips remain a go.

"We are currently working through some issues that the FAA has brought forth, but those issues are aside from the guided fishing and guided bear viewing trips that we provide," it reads. "The fishing has been great, and we assure our clients that Mavrik Aire Guide Service is still fully operational and their reservations are not in jeopardy in any way."
